Waterborne colored and clear fingernail polish

Abstract

A waterborne composition for application to fingernails and toenails includes an emulsified resin binder, coalescents, colored pigments, and additives. In a preferred embodiment, the emulsified resin binder is a phenyl ethylene-acrylic copolymer which is available in many different glass transition temperatures (Tg°c.=30° to 100°), each of which have different physical and chemical properties. The formulas for each specific Tg°c. vary in the types of polyol blends of acrylic copolymers. Although other values of Tg°c. may produce fair results, it was found that good results were obtained when a blend of Tg°c.=25 or lower (for flexibility) and Tg°c.=40 or higher (for hardness) were used.

What is claimed is:  
     
         1 . A nail polish composition comprising: 
 an emulsified non-toxic binder;    at least one coalescent; and    a non-toxic pigment portion.    
     
     
         2 . The nail polish composition as recited in  claim 1  wherein said emulsified non-toxic binder comprises a blend of phenyl ethylene acrylic copolymer emulsions having at least two different glass transition temperatures.  
     
     
         3 . The nail polish composition as recited in  claim 2  wherein said phenyl ethylene acrylic copolymer emulsions in said blend provide a first glass transition temperature Tg44° c. or higher and a second glass transition temperature of Tg25° c. or lower.  
     
     
         4 . The nail polish composition as recited in  claim 1  wherein said at least one coalescent is selected from the group consisting of: 
 propylene glycol N propyl ether;  
 N methyl-2-pyrroliosine;  
 propylene glycol methyl ether;  
 di-propylene glycol methyl ether;  
 tri-propylene glycol methyl ether; and  
 propylene glycol methyl ether acetate.  
 
     
     
         5 . The nail polish composition as recited in  claim 1  comprising at least two coalescents.  
     
     
         6 . The nail polish composition as recited in  claim 5  wherein said at least two coalescents include propylene glycol N propyl ether and N methyl-2-pyrroliosine.  
     
     
         7 . A nail polish composition comprising: 
 an emulsified non-toxic binder; and    at least one coalescent.    
     
     
         8 . The nail polish composition as recited in  claim 7  wherein said emulsified non-toxic binder comprises a blend of phenyl ethylene acrylic copolymer emulsions providing at least two different glass transition temperatures.  
     
     
         9 . The nail polish composition as recited in  claim 8  wherein said blend of polyethylene acrylic copolymer emulsions provides a first glass transition temperature of Tg25° c. or below and a second glass transition temperature of Tg44° c. or higher.  
     
     
         10 . The nail polish composition as recited in  claim 8  comprising one or more of said coalescents selected from the group consisting of: 
 propylene glycol N propyl ether;  
 N methyl-2-pyrroliosine;  
 propylene glycol methyl ether;  
 di-propylene glycol methyl ether;  
 tri-propylene glycol methyl ether; and  
 propylene glycol methyl ether acetate.  
 
     
     
         11 . A nail polish composition comprising: 
 an emulsified non-toxic binder comprising a blend of phenyl ethylene acrylic copolymer emulsions providing at least two different glass transition temperatures;    a blend of coalescents including propylene glycol N propyl ether and N methyl-2-pyrroliosine; and    a non-toxic pigment portion.
